Is Biogas Carbon Neutral? - What Is Carbon Neutrality of Anaerobic Digestion?

Biogas is a carbon-neutral fuel source. Is this true, however, for biogas utilization?

We can certainly state that biogas is carbon neutral, but the key difficulty is how to identify and maximize the potential for reduced GHG emissions from biogas use.

After all, carbon neutrality isn't going to help us battle climate change. If the biogas business is to assist cut carbon emissions, it will have to do a lot more than that.

The anaerobic digestion process, which creates biogas, has the potential to produce a "carbon footprint" of fossil fuel energy consumption, which, when combined together, works against the gas's inherent GHG neutrality. For maximal GHG reversal effects, the size of the footprint must be kept as small as feasible.

Is Biogas Carbon Neutral?

The extent of the "carbon footprint" (non-renewable energy uses that contribute to atmospheric GHGs) is a complicated computation that necessitates processing data from some of the greatest biogas facilities.

That is why we are glad to reproduce the following ADBA Press Release, which highlights current Bath University research:

The existing and prospective carbon footprints of AD are highlighted in an academic research.

A recent report from Bath University identifies the potential for biogas use to reduce GHG emissions.

In Wiltshire, Malaby Biogas' Bore Hill Farm Biodigester was featured in a research project sponsored by Supergen Bioenergy Hub and published by Bath University.

Using real-world data from 2019, the report shows how food waste recycling may significantly improve the climate advantages of renewable energy and green fertilizer for farms.

Previous work established the company's carbon-negative status, and this article now details the further greenhouse gas reductions that could be realized as a result of future actions.

This emphasizes the need for anaerobic digestion (AD) as a critical component of the Climate Emergency response.

AD is the unsung hero of the UK renewables boom, with a lack of regulatory backing in the draught Environment Bill and ELMS, as well as continual delays in the Waste and Resources Strategy rollout.
